Its totally possible that you got a defective one, it happens. ASC will give you some help.
I wired both of my Q's, a Q1, and a Q2 in backwords, different occasions and sent them back to ASC. They replaced them both for free both times. (rushing on race day)
Just send them a nice letter, dont be irate about it, and they will take care of you.
The only times I have seen them blow is when they get wired in backwords.
I have only seen my two and 3 others ever need to be sent back to asc of all the ones that I have sold through our shop.
